In a two-stage chemostat system, the volumes of the first and second reactors are V₁ = 500 l and V₂ = 300 l, respectively. The first reactor is used for biomass production and the second is for a secondary metabolite formation. The feed flow rate to the first reactor is F = 100 l/h, and the glucose concentration in the feed is S = 5.0 g/l. Use the following constants for the cells.

Determine glucose concentration in the effluent of the first stage. _____________________
